3 weeks ago, as I was leavng my marina, I noticed that my engine was running about 10 deg warmer than usual. I have been getting more than usual marine growth on the drive, so decided to head to shallow water and take a look. By the time I shut the engine down, 3 min, it was pretty hot. Jumped out of the boat and the drive was crusted up pretty bad. Cleaned everything off arounf the intake and hopped back in. Started right up and I gave it about 2200 RPM to see if I had water flow. At this poiunt the temp guage was showing about 180, but started climbing. So I abruptly stopped and shut her down. While waitng for the tow boat, I tried cranking the starter, but it was locked up. Got her towed in and up on the trailer. Found that the intake hose from the outdrive to the engine, had popped off at the drive. Abviously, that is why it overheated.
I went down to the marina last Sunday, exactly 2 weeks after the incident. Tried to crank her and still locked up. Started pulling plugs. 2 of the cylinders were completely filled with water. most of the rest were wet. I tapped it around to get most of the water out, then sprayed plenty of lube in each cylinder and let it sit for a day. Next day, I pulled the manifolds. They were also full of rusty water.
Changed oil. A little less than a quart of water in the bottom too. Put fresh oil and fresh plugs. Did a compression test and the readings were all over the place. I dont think I cranked it enough. On the second test things looked a little better, but still had 2 cylinders under 60lbs. I dont have alot of faith in my test, but tore 2 chunks out of my knuckles and called it quits for the day. Went back the next day and put the new plugs in and tried to start. Nothin. Cranked over but didnt fire. Checked for spark and it was good.
So, thats where I'm at. My guess is that the engine was hot. I stopped quick and either the flappers or the manifolds failed and cold water hit the head and cracked it. My boat is 100 miles from my house. I took a week vacation to go boating last week. Thats why I was able to work on it every day.
I think I am best to replace engine. Dont know what else to do to diagnose repair. I also think a repair would not be worth the money. Most anything that is done from this point on will be on the clock at the marina @ 85.00 hr.
I'm looking for some opinions from the experts.
Oh, most important. I want to get back in the water ASAP. Summer's running out. Here is the boat and engine info:
89 Sea Ray
260 Mercruiser 460 hrs (only 30 are mine)
No repair history that I know of.
Ran great all year.
The boat IS in salt water (chesapeake bay)
I recently had the Drive worked on and am disappointed that the hose popped off. That might be the fault of the tech that worked on it. The hose was old, little flexability. Should have been replaced.
Thanks Guys
